I bought a Paolo Mark E flat clarinet as I play one only occasionally, with younger pupils starting on the John Packer instrument. That is good but lacks certain keys and for a serious clarinettist the Paolo Mark, having full keywork, is better. The Mechanism needed adjustment on arrival but after that had been done I was impressed. I'll probably change the plastic mouthpiece; it's OK but I prefer ebonite. It plays as well in tune as most Eefers & I think it's great value for money. Next gig that requires one I'll happily use it.
